v4.0.0 - Open Workflow

Open Workflow SDK for Go v4.0.0

This release renames the project from Serverless Workflow to Open Workflow as part of the specification rebranding under the open-workflow-specification organization.

What changed

• New Go module path: github.com/open-workflow-specification/sdk-go/v4
• Rebranded all references from "Serverless Workflow" to "Open Workflow"
• Updated error type URIs from serverlessworkflow.io to open-workflow-specification.org
• Updated copyright headers to "The Open Workflow Specification Authors"

Migration

Update your imports:

// Before
import "github.com/serverlessworkflow/sdk-go/v3/parser"

// After
import "github.com/open-workflow-specification/sdk-go/v4/parser"

Then run:

go get github.com/open-workflow-specification/sdk-go/v4

Notes

• No API or schema changes — this is a naming/branding update only
• The project remains under CNCF governance
• Previous versions (v3.x and earlier) continue to be available under the old module path via proxy.golang.org
